WorkplaceDynamics worked with 30 publishing partners to poll more than a million employees from 872 large companies in order to compile a definitive list of 150 Top Workplaces with 1,000 employees or more, according to its website. The companies were selected based on feedback gathered through an objective employee survey using a proprietary set of questions.

The Top Workplaces list was first compiled in 2006, based on WorkplaceDynamics' belief that "The most successful companies are the ones that employees believe in," according to the company. It also compiles lists of the top workplaces by region in partnership with 37 leading publishers in the U.S.
